RESUMO

El 25% de los pacientes con Enfermedades Inflamatorias Intestinales (EII) se diagnostican antes de los 20 años. En la mayor parte de los centros del país se lleva a cabo la "transferencia" del paciente desde un centro de atención pediátrico a uno de adultos. La "transición" es un criterio de calidad con beneficios en el control de la EII reduciendo el número de recaídas, de hospitalizaciones y de cirugías. Por tal motivo hemos desarrollado un Programa Interdisciplinario de Transición entre dos hospitales de referencia nacional e internacional en EII. Materiales y métodos: Entre 1/2021 y 12/ 2022 se incorporaron 24 pacientes que ingresaron en 3 fases: Fase 1 Pacientes entre 14 y 16 años asistidos en el Hospital Garrahan (HG) con un abordaje interdisciplinario. Fase 2. A partir de los 17 años se realizaron 2 (dos) encuentros en el HG en conjunto con gastroenterólogos de adultos evaluando adherencia y autonomía y la Fase 3 llevada a cabo en el Hospital B. Udaondo (HBU) sólo con el equipo de adultos luego de 6 meses de realizada la transferencia evaluando adherencia al tratamiento, consultas a emergencias, internación y/o cirugías Resultados: Al inicio del Programa el 66% de los pacientes presentaban una actividad moderada a severa vs el 8% al finalizar la fase 3. Luego de la transferencia el 12,5% necesito ingreso a guardia e internación y un 8% tratamiento quirúrgico. El 83% de los pacientes continúan en seguimiento luego de 6 meses de haber sido transferidos (AU)

Twenty-five percent of patients with inflammatory bowel diseases (IBD) are diagnosed before the age of 20 years. In most centers in the country, the "transfer" of the patient from a pediatric to an adult care center is done. However, "transition" is a quality criterion with benefits in the control of IBD by reducing the number of relapses, hospitalizations, and surgeries. For this reason, we developed an Interdisciplinary Transition Program between two national and international reference hospitals in IBD. Materials and Methods: Between January 2021 and December 2022, we incorporated 24 patients into a three-phase program. Phase 1 involved patients between 14 and 16 years of age seen at Garrahan Hospital (HG) with an interdisciplinary approach. Phase 2 began from 17 years of age, with two meetings held at HG involving adult gastroenterologists to evaluate adherence and autonomy. Phase 3 was conducted at Hospital B. Udaondo (HBU) only with the adult team, six months after the transfer, evaluating adherence to treatment, emergency consultations, hospitalizations, and/or surgeries. Results: At the beginning of the program, 66% of the patients presented with moderate to severe disease activity, compared to 8% at the end of Phase 3. After the transfer, 12.5% of the patients required emergency department visits and hospitalization, and 8% required surgical treatment. Eighty-three percent of the patients continue in the program and are still being followed up six months after the transfer (AU)

RESUMO

Anti-tumor necrosis factor (TNF)-α treatment is an effective therapeutic option in intestinal inflammatory chronic disease in cases of the ineffectiveness of other drugs, but it promotes the development of opportunistic infections in their severe forms, due to the profound suppression of T-cell mediated immunity it produces. Among the most frequent are bacterial granulomatous infections, such as mycobacteria (especially tuberculosis), and fungal infections. Actinomycosis is a rare suppurative granulomatous chronic opportunistic infection, which in states of immunosuppression, such as the one caused after treatment with TNF blockers, is complicated by more severe clinical pictures.We present the clinical case, not previously described, of cervicofacial actinomycosis complicated with pneumonia, secondary to treatment with adalimumab in a patient with Crohn's disease.

El tratamiento con anticuerpos anti-factor de necrosis tumoral (TNF) es una opción terapéutica efectiva en la enfermedad inflamatoria crónica intestinal, en casos de ineficacia a otros fármacos, pero favorece la aparición de infecciones oportunistas en sus formas graves, debido a la gran inmunodepresión de células T que produce. Entre las más frecuentes se encuentran las infecciones granulomatosas bacterianas, como las causadas por micobacterias (en la que se destaca la tuberculosis), y las fúngicas. La actinomicosis es una infección oportunista crónica, granulomatosa, supurativa e infrecuente que, en estados de inmunosupresión, como el provocado tras el tratamiento con anticuerpos monoclonales anti-TNF, puede complicarse con cuadros clínicos más graves. Se presenta el caso clínico, no descrito anteriormente, de actinomicosis cervicofacial complicada con neumonía, secundaria al tratamiento con adalimumab, en una paciente con enfermedad de Crohn.

RESUMO

BACKGROUND: The prevalence of inflammatory bowel disease (IBD) is increasing globally, and the disease is frequently managed surgically. The aim of this study was to investigate the time trends and geographic distribution of IBD hospitalizations, surgeries and surgical-associated lethality. METHODS: Data from the Brazilian Health Public System were retrospectively collected regarding hospitalizations, in-hospital deaths, IBD-related surgical procedures and lethality from 2005 to 2015. RESULTS: This eleven-year period revealed decreases in the rates of hospitalization (24%), IBD-related surgeries (35%), and IBD-related surgical lethality (46%). Most surgeries were performed in Crohn's disease patients, and the predominant procedure was small bowel resection, mostly in young adults. A higher prevalence of ulcerative was observed throughout the country. The highest hospitalization and surgical rates were observed in the more industrialized regions of the South and the Southeast and in the municipalities integrated with metropolitan regions (MRs). The highest surgical-related lethality rates were seen in the less-developed regions and in municipalities not integrated with MRs. The length of hospital stay showed a slight increase throughout the period. CONCLUSIONS: Brazil follows the global trend of decreases in hospitalizations, lethality, surgeries, and surgical lethality associated with IBD. The unequal distribution of hospitalizations and surgeries, concentrated in the industrialized areas, but with a shift towards the Northeast and from urbanized to rural areas, indicates ongoing changes within the country. Reductions in the rates of IBD-related hospitalizations, surgeries and lethality suggest the effectiveness of decentralization and improvements in the quality of public health services and the advances in medical therapy during the study period.

RESUMO

Inflammatory bowel disease (IBD) is a chronic disease that requires chronic treatment throughout the evolution of the disease, with a complex physiopathology that entails great challenges for the development of new and specific treatments for ulcerative colitis and Crohn´s disease. The anti-tumor necrosis factor alpha therapy has impacted the clinical course of IBD in those patients who do not respond to conventional treatment, so there is a need to develop new therapies and markers of treatment response. Various pathways involved in the development of the disease are known and the new therapies have focused on blocking the inflammatory process at the gastrointestinal level by oral, intravenous, subcutaneous, and topical route. All these new therapies can lead to more personalized treatments with higher success rates and fewer relapses. These treatments have not only focused on clinical remission, but also on achieving macroscopic changes at the endoscopic level and microscopic changes by achieving mucosal healing. These treatments are mainly based on modifying signaling pathways, by blocking receptors or ligands, reducing cell migration and maintaining the integrity of the epithelial barrier. Therefore, this review presents the efficacy and safety of the new treatments that are currently under study and the advances that have been made in this area in recent years.

RESUMO

Appendiceal tumors comprise a variety of histologic types, including appendiceal mucinous neoplasms, which can be grouped as premalignant lesions, tumors of uncertain malignant potential, and malignant lesions. The appendiceal mucinous neoplasms are characterized by mucinous epithelial proliferation with extracellular mucin and pushing tumor margins, commonly an incidental finding during operative exploration. We report the case of a low-grade appendiceal mucinous neoplasm presenting as a subepithelial lesion in Crohn´s Disease patient. The diagnosis was not straightforward, and only surgical resection allowed an accurate diagnosis. Although Inflammatory Bowel Disease is a risk factor for the development of colorectal neoplasms, the absolute risk for appendiceal tumors is uncertain. The frequency of progression to malignancy remains to be determined.

RESUMO

Yersinia enterocolitica is a gram-negative rod causing intestinal infection in humans. It shows different clinical pictures with many different etiologies to be ruled-out, which sometimes makes it difficult to reach a timely and correct diagnosis. We report the case of an adolescent boy presenting with right lower quadrant pain from terminal ileitis with endoscopic findings akin to Crohn´s disease finally diagnosed as Yersinia enterocolitica, highlighting the usefulness of the different ancillary methods employed.

Yersinia enterocolitica es un bacilo Gram-negativo causante de infección intestinal en los humanos. Se presenta con diferentes cuadros clínicos que obligan a descartar una variedad de etiologías, lo cual, a veces, hace difícil alcanzar un diagnóstico correcto en forma oportuna. Se expone el caso de un varón adolescente con dolor en la fosa ilíaca derecha a partir de una ileítis terminal con hallazgos similares a la enfermedad de Crohn, que se diagnosticó, finalmente, como infección por Yersinia enterocolitica. Se destaca la utilidad de los diferentes métodos auxiliares empleados.

RESUMO

BACKGROUND: Recurrence is a common event after surgical resections secondary to Crohn's disease (CD). Endoscopic signs of inflammation, defined as postoperative endoscopic recurrence (PER) occur in up to 90% of the patients after one year. PER precedes clinical recurrence and further need for reoperations due to consequent bowel damage. Therefore, controlling inflammation after surgery in a preventive way is essential for disease control. OBJECTIVE: to review data regarding PER in CD, and demonstrate algorithms for its management after surgery. RESULTS: There is no fixed strategy to prevent recurrence after surgery in CD. There are several risk factors that must be taken into consideration to guide physicians to choose the best therapeutic agents and strategies in this scenario. In this review, the authors describe in details the stratification based on risk factors, the therapeutic agents mostly used to prevent recurrence and discuss the several options for the postoperative management in CD. CONCLUSIONS: No fixed strategy is recommended after surgical resections in CD. Thus, the need for a personalized approach for each patient is emphasized, in accordance with several conditions and variables.

RESUMO

Biological therapies have been essential for the management of inflammatory bowel disease; however, their high cost results in many patients being unable to access them. With time, commercial patents of many "original" biologics are reaching or almost in the point of reaching the expiration date of their licenses, which has allowed for the development of new agents known as biosimilars leading to a reduction of the cost of these therapies. The objective of this review is to explain what biosimilars are and show evidence of their effectiveness and safety.

Las terapias biológicas son parte fundamental en el manejo de la enfermedad inflamatoria intestinal, sin embargo los costos de éstas han hecho que muchos de los pacientes que tienen indicación de su uso, no puedan utilizarlas. Con el paso del tiempo, muchos biológicos "originales" están alcanzando o a punto de alcanzar el vencimiento de sus patentes, lo que ha llevado al desarrollo de nuevos agentes conocidos como biosimilares, determinando una disminución en los costos de estas terapias. Esta revisión tiene como objetivo explicar en qué consisten los biosimilares y la evidencia actual con respecto a su eficacia y seguridad.

RESUMO

ABSTRACT BACKGROUND The nutritional status of individuals with inflammatory bowel diseases is directly related to the severity of the disease and is associated with poor prognosis and the deterioration of immune competence. OBJECTIVE To assess the nutritional status and the body composition of outpatients with inflammatory bowel diseases. METHODS A cross-sectional study was conducted with clinical and nutritional assessment of patients with Crohn’s disease and ulcerative colitis. Patients were classified according to the clinical activity through Crohn’s Disease Activity Index and Mayo Score. Nutritional assessment consisted of anthropometric measurements of current weight, height, mid-arm circumference, triceps skinfold thickness and thickness of adductor policis muscle, with subsequent calculation of BMI, arm muscle circumference and the mid-arm muscle area (MAMA). The phase angle (PhA) and lean and fat mass were obtained with the use of electrical bioimpedance. Descriptive statistics, chi-square test or Fisher exact test, ANOVA and t-test. RESULTS We evaluated 141 patients of which 54 (38.29%) had Crohn’s disease and 87 (61.70%) ulcerative colitis. The mean age was 43.98 (±15.68) years in Crohn’s disease and 44.28 (±16.29) years for ulcerative colitis. Most of the patients were in clinical remission of the disease (Crohn’s disease: 88.89%; ulcerative colitis: 87.36%). Regarding the nutritional classification using BMI, it was found that 48.15% of Crohn’s disease patients were eutrophic and 40.74% were overweight or obese; among patients with ulcerative colitis, 52.87% were classified as overweight or obese. When considering the triceps skinfold, it was observed in both groups a high percentage of overweight and obesity (Crohn’s disease: 75.93%; ulcerative colitis: 72.42%). Crohn’s disease patients showed the most affected nutritional status according to the nutritional variables when compared to patients with ulcerative colitis (BMI: 24.88 kg/m² x BMI: 26.56 kg/m², P=0.054; MAMA: 35.11 mm x MAMA: 40.39 mm, P=0.040; PhA: 6.46° x PhA: 6.83°, P=0.006). CONCLUSION Patients with inflammatory bowel diseases have a high prevalence of overweight and obesity. Crohn’s disease patients had more impaired anthropometric and body composition indicators when compared to patients with ulcerative colitis.

RESUMO CONTEXTO O estado nutricional de indivíduos com doença inflamatória intestinal está diretamente relacionado à gravidade da doença e associado a mau prognóstico e deterioração da competência imune. OBJETIVO Avaliar o status e a composição corporal de pacientes ambulatoriais com doença inflamatória intestinal. METÓDOS Foi conduzido um estudo transversal com avaliação clínica e nutricional de pacientes com doença de Crohn e colite ulcerativa. Pacientes foram classificados de acordo com o índice de atividade clínica Crohn’s Disease Activity Index e escore de Mayo. Avaliação nutricional foi composta peso atual, estatura, circunferência do braço, dobra cutânea tricipital e espessura do músculo adutor do polegar. Posteriormente, foram calculados índice de massa corporal, circunferência muscular do braço e área muscular do braço corrigida. O ângulo de fase e massa magra e massa gorda foram derivadas da bioimpedância elétrica. Foram realizados análise descritiva, teste de qui-quadrado ou exato de Fisher, teste t e ANOVA. RESULTADOS Foram avaliados 141 pacientes, sendo 54 (38,29%) com doença de Crohn e 87 (61,70%) com colite ulcerativa. A idade média foi de 43,98 (±15,68) anos em pacientes com doença de Crohn e 44,28 (±16,29) anos em pacientes com colite ulcerativa. A maioria dos pacientes estava em remissão clínica da doença (doença de Crohn: 88,89%; colite ulcerativa: 87,36%). O estado nutricional de acordo com o IMC foi 48,15% eutrófico e 40,74% sobrepeso/obesidade para doença de Crohn; entre os indivíduos com colite ulcerativa, 52,87% foram classificados como sobrepeso/obesidade. Ao se considerar dobra cutânea do tríceps, observou-se obesidade em ambos os grupos (doença de Crohn 75,93%; colite ulcerativa: 72,42%). Pacientes com doença de Crohn apresentam maiores variações de composição corporal quando comparados com pacientes com colite ulcerativa (IMC: 24,88 kg/m² x IMC: 26,56 kg/m², P=0,054; área do músculo do braço: 35,11mm x área do músculo do braço: 40,39 mm, P=0,040; ângulo de fase: 6,46° x ângulo de fase: 6,83°, P=0,006). CONCLUSÃO Pacientes com doença inflamatória intestinal apresentaram alta prevalência de sobrepeso e obesidade. Indivíduos com doença de Crohn apresentaram parâmetros de composição corporal e de antropometria mais comprometidos, quando comparados com indivíduos com colite ulcerativa.

RESUMO

We report the case of a 64-year-old patient diagnosed with extensive ileal Crohn´s disease who developed Guillain-Barré syndrome after starting biological therapy with adalimumab. Neurologic involvement associated with inflammatory bowel diseases is recognized as an extra-intestinal manifestation. After the breakthrough of antitumor necrosis factor alpha (anti-TNF-α) agents, an increasing number of cases of acute inflammatory demyelinating polyneuropathies have been reported; however, only one case has been described in a patient with Crohn´s disease. Although a causal relationship between Guillain-Barré syndrome and TNF-α antagonist therapy cannot be proven, this report emphasizes the need to monitor for neurologic signs and symptoms in patients with inflammatory bowel diseases, with or without biological therapy, to avoid severe and irreversible complications associated with demyelinating diseases.

RESUMO

Patients with inflammatory bowel disease (IBD) have shown to be at increased risk of developing extraintestinal malignancies. Immunomodulators (immunosuppressant and anti-tumor necrosis factor) diminish the mucosal inflammatory response changing the evolution of the disease, especially when these strategies are introduced earlier. However, therapies that alter the immune system may also promote carcinogenesis. Treatment of IBD in patients with prior malignancy is challenging and the final decision regarding therapeutic strategy should be made on a case-by-case basis. The purpose of this review is to show the characteristics of extra-colonic cancer in patients with IBD, including risks, pathogenesis and management of IBD after cancer diagnosis, the effect of neoplasm treatment on IBD, and the effect of IBD and its treatments on cancer outcomes.

Los pacientes con enfermedad inflamatoria intestinal (EII) presentan un mayor riesgo de desarrollar neoplasias extraintestinales. Los inmunomoduladores (inmunosupresores y terapia biológica anti-TNF) disminuyen la respuesta inflamatoria a nivel de la mucosa, modificando la evolución de la enfermedad, especialmente cuando son introducidos precozmente. Sin embargo, estas terapias pueden alterar el sistema inmune y promover la carcinogénesis. El tratamiento de la EII en pacientes con antecedentes de cáncer es un desafío y la decisión final sobre la estrategia terapéutica debe ser determinada caso a caso. Esta revisión tiene como objetivo mostrar las características de las neoplasias extra-intestinales en pacientes con EII, incluyendo los riesgos, patogénesis y manejo de la EII posterior al diagnóstico del cáncer, el efecto de la neoplasia sobre el tratamiento de la EII y el efecto de la EII y su tratamiento sobre el cáncer.

RESUMO

Inflammatory bowel disease (IBD) is a chronic, idiopathic disease characterized by inflammation of the gastrointestinal tract. It affects more than 5 million people worldwide and in Chile studies suggest that IBD incidence has increased in recent years. It is manifested by periods of remission and activity, requiring permanent pharmacological treatment. Both, the occurrence of a crisis episode and the need for lifetime medical treatment could affect the quality of life of IBD patients. Studies suggest that patients with IBD require education to develop self-management of their disease and adhere to treatment, thus reducing the risk of crisis episodes. The importance of this strategy or action is significant if we consider that studies have shown that the level of knowledge of IBD patients regarding their pathology is low. The purpose of this article is to review the effect of education on the management of IBD patients and the implications of a multidisciplinary team with an IBD specialist nurse.

La enfermedad inflamatoria Intestinal (EII) es una enfermedad crónica, idiopática, caracterizada por la inflamación del tracto gastrointestinal. Afecta a más de 5 millones de personas en el mundo y en Chile estudios sugieren que ha ido en aumento en los últimos años. Se manifiesta por períodos de remisión y actividad, siendo necesario un tratamiento farmacológico permanente. Tanto la presencia de crisis como la necesidad de un tratamiento médico de por vida, podrían afectar la calidad de vida de estos pacientes. Estudios sugieren que los pacientes con EII requieren de educación para poder desarrollar un buen autocuidado de su enfermedad, adherirse al tratamiento y disminuir así el riesgo de crisis. Esta estrategia o acción no deja de ser importante si consideramos que estudios han mostrado que el nivel de conocimiento de los pacientes con EII respecto a su patología es bajo. El propósito de este artículo es revisar el efecto de la educación en el manejo de los pacientes con EII, y las implicancias de un equipo multidisciplinario con una enfermera especialista en EII que realice el seguimiento de estos pacientes.

RESUMO

Benign multicystic peritoneal mesothelioma is an uncommon lesion arising from the peritoneal mesothelium. It is asymptomatic or presents with unspecific symptoms. Imaging techniques may reveal it, however the final diagnosis can only be made by histopathology. Surgery is the only effective treatment considering its high recurrence rate. We report a 19 years old male with Crohn’s disease. Due to persistent abdominal pain, an abdominal magnetic resonance imaging was performed, showing a complex cystic mass in the lower abdomen. The patient underwent surgery and the lesion was completely resected. The pathological study reported a benign multicystic peritoneal mesothelioma.

RESUMO

Crohn’s disease (CD) and ulcerative colitis (UC) are immunologically mediated chronic digestive diseases, with a trend to progressive damage, which generally have an onset at young age and a course characterized by remission and relapse. Its incidence and prevalence present a steady upward trend globally. CD is characterized by transmural inflammation in the digestive tract and it is a complex disease. The perianal involvement –“p”, abscesses or perianal fistulas– is considered a condition that is different from penetrating phenotype, a condition that indicates an aggressive behavior of CD. Early identification and proper treatment of fistulas, including correct diagnosis and classification are essential elements to establish an appropriate treatment plan. A multidisciplinary approach is essential including medical and surgical approach.

La Enfermedad de Crohn (EC) y la colitis ulcerosa (CU) son enfermedades digestivas crónicas, progresivas, mediadas inmunológicamente, que en general, tienen un inicio durante la edad adulta-joven y un curso que se caracteriza por remisión y recaída. Su incidencia y prevalencia ha presentado una tendencia constante de incremento a nivel global. La EC se caracteriza por comprimo transmural del tracto digestivo y por ser una patología compleja. El compromiso perianal –“p”, abscesos o fístulas perianales– se considera una condición diferente al fenotipo penetrante, señalándose en la actualidad como una variable modificadora del comportamiento de la patología y de gravedad. La identificación dirigida y precoz de trayectos fistulosos, su correcto diagnóstico y clasificación son elementos primordiales para poder establecer un plan terapéutico apropiado. Es imprescindible un abordaje multidisciplinario, en el cual exista integración médico-quirúrgica.

RESUMO

Biological therapy plays an important role in the treatment of inflammatory bowel disease (IBD). However, the use of these drugs is limited due to fears about their side effects. Aim: To report the experience with the use of infliximab/adalimumab in IBD patients in a public hospital. Material and Methods: Descriptive study of a historical cohort of IBD patients treated with infliximab and adalimumab between April 2012 and July 2014. The clinical response was considered favourable when general, intestinal and extra intestinal symptoms subsided after the induction therapy. In addition, endoscopic and/or imaging response was evaluated at three and six months of treatment. Results: Fifteen out of 162 patients, aged 17 to 52 years (7 women) were included. Seven had Crohn´s Disease, 7 had ulcerative colitis and one had non-classifiable IBD. Biological therapy was indicated due to conventional refractory disease in all patients. All patients received combined treatment with immunosuppressive medications. A favorable clinical response was observed in 93 percent after induction therapy and 73 percent showed endoscopic/imagining remission after 3-6 months. Only one patient experienced side effects associated to the biological therapy, which did not result in discontinuation or treatment interruption. Conclusions: In this cohort of IBD patients treated in a public hospital, the use of infliximab/adalimumab was associated with favorable clinical and endoscopic evolution, post induction therapy with no major side effects.

La terapia biológica tiene un papel fundamental en el tratamiento de la enfermedad inflamatoria intestinal (EII). Sin embargo, el uso de estos fármacos es escaso debido a los costos y los temores sobre los efectos secundarios. Objetivo: Dar a conocer la experiencia en el uso de infliximab/adalimumab en pacientes con EII atendidos en un hospital público de nuestro país. Material y Métodos: Estudio descriptivo de una cohorte histórica de pacientes con EII tratados con infliximab y adalimumab entre abril de 2012 y julio de 2014. La respuesta clínica fue considerada favorable cuando los síntomas generales, intestinales y extra-intestinales desaparecieron después de la terapia de inducción. Además se evaluó la respuesta endoscópica/radiológica a los 3 y 6 meses de tratamiento. Resultados: De un total de 162 pacientes con EII, 15 fueron tratados con terapia biológica, con edad entre 17-52 años (7 mujeres). Siete presentaban el diagnóstico de enfermedad de Crohn, siete colitis ulcerosa y uno EII no clasificable. En todos se inició terapia biológica debido a la presencia de refractariedad a la terapia convencional. Todos recibieron terapia combinada con inmunosupresores. Se observó una respuesta clínica favorable en 93 por ciento después de la terapia de inducción y 73 por ciento tuvo una mejoría endoscópica después de 3-6 meses. Sólo un paciente presentó un evento adverso a terapia biológica, el cual no motivó la interrupción del tratamiento. Conclusiones: En esta cohorte de pacientes con EII tratados en un hospital público, el uso de infliximab/adalimumab se asoció con mejoría clínica y endoscópica post terapia de inducción, sin mayores efectos secundarios.

RESUMO

Crohn’s disease (CD) is a type of inflammatory bowel disease that may involve every segment of the entire gastrointestinal tract and is characterized by transmural inflammation and formation of granulomas. Its classic presentation is evidenced by fever, abdominal pain and signs of intestinal obstruction, however these signs could vary among patients. Fistulizing CD (FCD) is a less frequent presentation. The clinical signs and symptoms of this form are not characteristic and usually have a more complicated outcome due to the development of sepsis. Certolizumab pegol is a recombinant humanized antibody, targeting the tumor necrosis factor alpha (TNF-alpha), which has been effective in patients with fistulizing CD. In this article, we report a patient with complicated FCD who required 21 month hospitalization due to the presence of multiple fistulae and malnutrition, but who had a successful management with certolizumab pegol.

La enfermedad de Crohn (EC) es un tipo de enfermedad intestinal inflamatoria, que puede comprometer cualquier segmento del tracto gastrointestinal caracterizado por inflamación transmural y formación de granulomas. Su presentación clínica clásica se caracteriza por fiebre, dolor abdominal y signos de obstrucción intestinal, aunque estos signos pueden variar entre cada paciente. La EC fistulizante (ECF) es un tipo de presentación menos frecuente. Los síntomas y signos clínicos no son fácilmente definidos y usualmente se asocian con el desarrollo de sepsis. El certolizumab pegol es un anticuerpo monoclonal recombinante contra el factor de necrosis tumoral alfa. En este artículo se describe la evolución clínica de un paciente con ECF con múltiples complicaciones y quien requirió una hospitalización prolongada durante 21 meses debido a la presencia de múltiples fístulas y desnutrición, quien respondió satisfactoriamente al tratamiento con certolizumab pegol.

RESUMO

La enfermedad de Crohn (EC) es protagonista fundamental de la llamada enfermedad inflamatoria intestinal (EEI), término con el que se conocen varias entidades cuyo origen es multifactorial y se caracterizan por un fenómeno inflamatorio, crónico, recurrente con diferentes grados de afectación sobre el tubo digestivo; pero además con compromiso potencial de otros órganos. En la última década ha habido un renovado interés en dichas entidades, debido a un auge en medicamentos novedosos, a pesar de lo cual estas siguen siendo incurables. Lo anterior asociado a una incidencia creciente de dicha patología en nuestro país nos obliga tanto científica como moralmente a elaborar unos lineamientos básicos, prácticos con listas de chequeo adaptadas a nuestro medio para el enfoque diagnóstico y seguimiento a través de las primeras consultas del paciente con EC.

Crohn’s disease (CD) is the fundamental protagonist of so-called Inflammatory Bowel Disease (IBD). This is a term by which several entities are known. Its origin is multifactorial. It is characterized by chronic and recurrent inflammation with different degrees of involvement of the gastrointestinal tract, but also with potential commitment of other organs. In the last decade there has been a renewed interest in these entities due to a boom in innovative medicines. Despite these medications, CD and IBD remain incurable. The increasing incidence of CD in our country requires us both scientifically and morally to develop basic, practical guidelines with checklists adapted to our environment for the diagnosis and management of CD through the first consultations of patients.
